DIBOND is a prefabricated panelling material,i.e. the surface of the standard panel is eitherlacquered, anodised or laminated with a self-adhesive foil. These surfaces are protected bya special foil during transport, storage andprocessing.

Nevertheless, the following information mustbe observed when storing and handling thepanels:

• The pallets must be handled carefully duringtransport and unloading.

• Upon delivery the pallets must be examinedfor any damage due to moisture (DIBONDpanels that have become wet must be dried toavoid any spots or corrosion forming). Anydamage must be reported immediately andconfirmed by the forwarding agent.

• Store the pallets so that they are protectedagainst any wetness penetrating due to rainand spray water and avoid any condensationforming (e.g. when transporting cold panels towarmer rooms).

• Store the pallets stacked one over the other(do not store DIBOND panels standingvertically), with a maximum of 6 pallets of thesame format stacked on top of each other(heavy pallets at the bottom).

• Individual panels must be lifted off thepallet by two people holding all four cornersand not drawn over each other. Carry thepanels vertically. Wear gloves to avoid makingany marks on them.

The following should be observed asregards the DIBOND protective foil:

• Storage exceeding 6 months should beavoided. In the case of longer storage, thepanels should be rubbed – after removing theprotective foil – with a cloth moistened withmethylated spirit.

• Strong fluctuations in temperature reducethe long-term durability. Remove the protectivefoil prior to outdoor applications (no resistanceagainst ultraviolet).

• Should the protective foil partially come offduring processing, dirtied edges can occur inthe course of time.

Routing

DIBOND can be easily routed on conventionalrouting machines and CNC machining centres.

To avoid pressure marks on the DIBONDsurface, please use plastic or wood vice jawswhen chucking the workpieces.

High-speed steel or carbide tipped cutterssuitable for aluminium and DIBOND have awide tooth pitch, radiused and smooth groovesand small lip angles.

They produce perfect cuts, e.g. under thefollowing conditions:

• High-speed steel (HSS), max. cutting speed 3000 m/min.,max. feed 25m/min.

• Carbide tipped (CT), max. cutting speed 5000 m/min.,max. feed 30 m/min.

Drilling

DIBOND can be drilled with twist drills nor-mally used for aluminium and plastics onmachines common for metals.

Drill material: High-speed steel (HSS)

Tool geometry:Lip angle: 100° - 140° or spot facing cutterwith centre-point.

Angle of twist: 30° - 45°

Countersinking

Three-lipped core drills and counterborescommon for aluminium are used for counter-sinking pre-drilled holes. Counterbored holesare less out of centre than those produced bytwist drills. Countersinks for aluminium can beused for countersinking flat head screws intoDIBOND. Head and shank counterbores foraluminium are mainly used for countersinkingscrew heads or for making holes throughDIBOND.

Contour cutting

DIBOND can be cut to size with water torches,profile milling machines, contour saws and jigsaws. Please cut abrasively when using awater torch. Pre-drilling of the panels is neces-sary when starting the cut in the middle of apanel as it is not possible to drill through witha water torch.

Shearing

DIBOND is easily sheared with a guillotine. A slight drawing of the aluminium cover sheetcaused at the impact side should be noted.The clamp on the shear should be fitted with ashock-absorbing rubber pad to prevent damageto the cover sheet.

Punching

DIBOND panels of any thickness can bepunched with conventional sheet punchingmachines. For clean cuts please use evenlyground tools and the narrowest possiblecutting gap. This punching method also causesa slight drawing of the panel cover sheet.

Bending

DIBOND can be formed by conventional metaland plastic fabrication methods. Certainspecific points should be noted relating to themultilayer structure combining materials ofdifferent characteristics.

• The minimum radius is r = 15 x d

The spring-back effect experienced when fold-ing sheet metal is larger with DIBOND. Forproduction series a prototype should be made.

The surface should be protected from damageby affixing plastic film or inserting polyethyl-ene of 1 – 2 mm thickness or plastic film stripsduring processing.

Bending with a brake press

(Fig. 1) DIBOND, like sheet metal, is easilyformed with a brake press. The air-bendingprocess is used when forming with a brakepress.

The DIBOND panel rests on the edges of thedie (rails, channels) and is bent by the punch(tube or shaft). The bending angle is deter-mined by the width of the die and the stroke ofthe punch. The die edges should be roundedand smooth.

Ideal die width:2 x t + 2 x protective foil thickness + punch diameter + 15 mm

The minimum side length of the bent partshould be 5 times the DIBOND thickness.

Bending with a folding machine

(Fig. 2) When working with folding machines,the panel to be bent is clamped between twocheeks. The projecting edge is bent around theupper clamping cheek and former using themovable swivel bar. The bending radius isdetermined by interchangeable formersattached to the upper clamping cheek.

Bending with a roll bending machine

DIBOND can be bent with sheet metal rollbending machines – mainly with three andfour-roll machines. Please make sure that thefeeder does not exert too much pressure.

Bending rolls which are also used for bendingother metals must be thoroughly cleaned fromswarf before processing DIBOND. We recom-mend ground rolls to avoid damaging the coversheets.

Method

DIBOND composite panels can be shaped bymeans of a simple processing technique. Thisprocedure, the routing and folding technique,enables a variety of shapes and sizes to bemanufactured.

V-shaped or rectangular grooves are routed onthe rear of the panels with disk or end millingcutters, whereby the aluminium cover sheet atthe front and part of the polyethylene core areretained. The small thickness of the remainingmaterial then allows folding by hand. A brakepress is not required. The groove shape deter-mines the radius of the bend.

The grooves can be produced with both apanel saw with routing device for DIBOND anda hand routing machine. The routing and fold-ing technique can be used for composite pan-els of all standard surfaces.

jointing /

techniquef ixing

DIBOND can be joined by means of standardprocesses used in metal and plastics tech-nology.

If DIBOND is to be joined to structural parts ofmetals other than aluminium, or if fasteners(e.g. bolts, screws) are to be used, the follow-ing material guidelines should be observed:

Fasteners and structural parts made ofaluminium, plastic or stainless steel should besuitable for the assembly with DIBOND.

When using other materials please insertinsulating washers etc. or apply protectivecoating to prevent corrosion.

Please take the thermal expansion of the panelinto account for outdoor use of DIBOND toavoid jamming or deformation.

The minimum gap depends on the expectedexpansion of the panel.

Please refer to processing recommendationsfor rivets and bolts for additional measures toprevent jamming.

The linear thermal expansion of DIBOND isdetermined by the aluminium cover sheets. Ata temperature difference of 100 K the longitu-dinal deformation is 2.4 mm/m.

16

Please take the thermal expansion of theDIBOND panel into account when riveting foroutdoor use. To avoid jamming, the hole in thepanel must be large enough to allow forexpansion.

DIBOND panels can be fastened together orjoined to other materials with rivets commonto aluminium constructions (Fig. 1).

For outdoor use and for use in areas of highhumidity, aluminium blind rivets with stainlesssteel mandrils should be used to prevent uglycorrosive edges. When using aluminium blindrivets with steel mandrils, the mandril shoulddrop out after riveting (detachable version).

To prevent jamming the panel, the rivet shouldbe fitted into the panel hole with a rivetattachment jig (Fig. 2) to avoid excessive pres-sure of the rivet onto the panel. The attach-ment jigs are obtainable from manufacturersof blind rivets with an attachment head diame-ter of 11 or 14 mm.

Countersink rivets do not allow for panelexpansion and are therefore unsuitable foroutdoor use.

Important:If no attachment jig is used, please removeprotective foil prior to riveting.

Threaded fasteners for indoor use

Sheet metal and wooden screws with differenthead-shapes are suitable for indoor use (Fig. 1). They do not normally allow for anypanel expansion.

Countersink screws can be inserted by theusual countersinking method or by depressingthe aluminium surface into the panel. Whendepressing the aluminium surface, the holediameter in the panel must be larger than thescrew diameter.

Important:

Make sure to remove protective foil prior toscrewing.

Threaded fasteners for outdoor use

Please take thermal expansion of the DIBONDpanel into account when using threaded fas-teners outdoors. To avoid jamming, the holediameter in the panel must allow for theexpansion.

Fastening without jamming is possible withfascia screws (Fig. 2). Please make sure that thescrews are not too tight.

Hot-air welding has proved useful for joiningthermoplastic plastics and for weldingDIBOND. The plastic core and the plasticwelding rod are heated and welded withelectrical hot-air welding sets. The followingconditions are essential for good results:

• Well prepared welding joint

• Good quality welding rod

• Clean hot air

• Correct temperature

• Correct contact pressure

• Welding speed

Welding with rapid welding nozzle

(Fig. 1) The rapid welding nozzle methodensures uniform heating of the core materialand the welding rod and thus results in abetter welding quality. Rod A is insertedmanually through nozzle tongue B. By applyingconstant pressure to the nozzle tongue, the rodis pressed into the joint.

Preparation of welding joint

For butt-welding, the edges of the DIBONDpanels must be chamfered (Fig. 2).

As the plastic core oxydizes relatively quicklywhen exposed to air, welding should be com-pleted within 24 hours after chamfering.

Welding rod

Please use the following quality:

Polyethylene, soft, Type: 1800-h

Colour: black, diameter: 3-4 mm

The outer layer (oxide layer) of the welding rodshould be removed with emery cloth immedi-ately before welding. Please chamfer thestarting end of the rod to approx. 45°.

Temperature

The following air temperature is required forhot-air welding:

DIBOND: 265°C +/- 5°C

The temperature must be continuouslyadjustable and is measured with a mercurythermometer or bimetal measuring unit 5 mmfrom the nozzle point. To measure the temper-ature, please take off the rapid welding nozzle.

Contact Pressure

The required pressure to the nozzle shoe (rapid welding nozzle) should be approx. 3 kp.

Hot-air welding sets

We recommend using the Leister hot-airwelding set, Type DIODE PID, in connectionwith the ventilator, Type MINOR.

Skimming the welding seam

A scraper blade or knife is used at a very flatangle to shave the welding seam as soon as ithas cooled down. For visible welding joints,the seam on butt and corner welds is removedusing a crescent-shaped knife (Fig. 3).

Any suitable connection or shock-resistantframe can easily be made with aluminiumsections.

The inevitable tolerances signify differentretention forces. A uniform and solid fit of thesections is obtained by pressing the sectionsides together prior to inserting the panels.

Butt joint, corner and edge sections are avail-able for panels of 3, 4 and 6 mm (Fig. 3).Please ask for our stock list.

Adhesive sealing compounds

Surface treatment /Screen printing

The aluminium treatment and priming carriedout at the factory in a continuous process withcontinuous quality control is advantageous tothe overlacquering of the stove-lacqueredDIBOND surface.

DIBOND overlacqueringprocedure

• Pre-cleaning of the panels using methylatedspirit

• Grinding the surfaces with wet abrasivepaper (grain size 360)

• Removing grinding dust with a lintfree clothmoistened with spirit

• For the top coat, please follow the instruc-tions of the top coat suppliers

Any information given with regard to overlac-quering does not apply to DIBOND SR panels.

The composition of lacquer coating forDIBOND is basically the same as those for millfinish aluminium surfaces. However, it isadvisable to be familiar with coating systemsand materials as well as working methods foraluminium.

Additional information

• For general information on painting,lacquering and coating of aluminium werecommend the leaflets on ”02, 03, 012, 015surfaces” issued by

AluminiumzentralePostfach 101 262D-40003 Düsseldorf.

Stove-lacquered DIBOND panels are wellsuited for screen printing.

Prior to printing, please make sure to clean thesurface with methylated spirit.

Practice has shown that even within a givenspecification of stove lacquer paint and print-ing ink there may be variances, and in view ofthis it is recommended that in the case of eachparticular application the adhesion propertiesof the selected printing ink should be tested.

In order to achieve certain surface characteris-tics or to improve mechanical or chemicalresistance it may be useful to overlacquer theprint.

Please follow the instructions of the printingink suppliers.

The above information does not apply toDIBOND SR panels.

Please note:

• The maximum permissible temperatureof the material (DIBOND panels) mustnot exceed 70° when applying fast-dry-ing methods. During the drying processat high temperatures the DIBOND pan-els must be positioned with great careto prevent deforming.

• DIBOND cut edges should not be in contactwith organic solvents for a prolonged periodof time to avoid weakening the bond.

• DIBOND panels lacquered or overlacqueredat a later stage should not be bent or folded.The lacquer in the bends or folds may bedamaged due to the low elasticity of the topcoat.

• Only inferior lacquer adhesion can beachieved on core material exposed at cutedges.

• Please make a test prior to overlacqueringand follow the instructions of the lacquersuppliers.
